HOW TO: Preserve device permissions/settings with RealPort in Linux

Most newer Linux distribution versions and kernels now use UDEV for device creation. This means the settings applied via dgrp_cfg_node or dgrp_gui will no longer work to preserve device permissions/ownership. For systems using UDEV all permissions are now set by UDEV, the driver dgrp_gui/dgrp_cfg_node permission settings no longer control these settings on newer kernels/distributions.

With UDEV, you can modify the permissions by modifying the RealPort UDEV script, called "10-dgrp.rules" in /etc/udev/rules.d.

Here are the default entries found in /etc/udev/rules.d/10-dgrp.rules:
